next/image does not load images from external URL after deployment

Question

I use the Next.js Image component for image optimization. It works great on dev but it doesn't load images from external URLs in production.

What can I do?

Answer 1

You need to set the configuration in the next.config.js file first.

For Example:

on next.config.js

module.exports = {
    images: {
        domains: ['images.unsplash.com'],
    },
}

on pages/your_page_file.tsx

<Image
    alt="The guitarist in the concert."
    src="https://images.unsplash.com/photo-1464375117522-1311d6a5b81f?ixlib=rb-1.2.1&ixid=MXwxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHw%3D&auto=format&fit=crop&w=2250&q=80"
    width={2250}
    height={1390}
    layout="responsive"
/>

For versions above 12.3.0 this is the accepted approach:

module.exports = {
    images: {
        remotePatterns: [
            {
                protocol: 'https',
                hostname: 'assets.example.com',
                port: '',
                pathname: '/account123/**',
            },
        ],
    },
}

I noticed you're having trouble with next/image not loading external images after deployment. I faced a similar issue, and after some tweaking, here's the configuration that worked for me:

/** @type {import('next').NextConfig} */
const path = require('path')

const nextConfig = {
  images: {
    remotePatterns: [
      {
        protocol: 'https',
        hostname: '**',
        port: '',
        pathname: '**',
      },
    ],
  },
}

module.exports = nextConfig

Feel free to give this configuration a try, and let me know if it resolves your problem. If you have any other questions or run into further issues, I'm here to help!

For future references, I was having the same problem after deploying my next.js site to Netlify. Only later, reading my logs, I found

Image domains set in next.config.js are ignored. Please set the env variable NEXT_IMAGE_ALLOWED_DOMAINS to "cdn.sanity.io" instead

So this is probably something to note. In the meanwhile before I saw it, I plugged this next-sanity-image plugin https://www.sanity.io/plugins/next-sanity-image to my page, which also bypassed the problem

If you want to display any images in nextjs app from accross the internet; here is my next config:

const nextConfig = {
    reactStrictMode: true,
    i18n,
    sassOptions: {
        includePaths: [path.join(__dirname, 'src/styles')],
        prependData: `@import "variables.scss";`,
    },
    images: {
        remotePatterns: [
            {
                protocol: 'https',
                hostname: '**',
                port: '',
                pathname: '**',
            },
        ],
    },
}

Answer 5

Add and declare your domain in your next config, next.config.js:

module.exports = {
    reactStrictMode: true,
    images: {
        domains: ["yourDomain.com"],
        formats: ["image/webp"],
    },
};

The configuration file, next.config.js, should be in the root of your project.

And lastly, restart project even in dev mode.

For me was just add blocker extension.
